Radon: Zone 1 — High Risk· State-level data

Sioux Falls sits in the southeast corner of South Dakota on the Big Sioux River, where a continental climate, clay-heavy soils, and a housing stock that spans more than a century create a well-defined set of inspection priorities. Basement water intrusion is the leading finding across the metro area; spring snowmelt and heavy summer rains test sump pumps, window wells, and perimeter drain systems that older homes may never have had properly installed. The city has a growing inventory of newer construction on its expanding suburban perimeter, but older neighborhoods near the falls and downtown contain pre-1950 homes with original plumbing, wiring, and foundation systems that require careful evaluation. South Dakota's winters are severe, and ice damming at eaves is a recurring issue on homes with inadequate attic insulation or blocked soffit vents. Radon levels in Minnehaha County are elevated, reflecting the regional geology across eastern South Dakota, and testing is advisable on any property. There are 6 inspectors in the Sioux Falls area.

Foundation Issues on Expansive Bentonite Clayhigh

Western South Dakota has extensive bentonite clay deposits — one of the most expansive soil types in existence. Foundation movement is a pervasive and serious issue in Rapid City and the Black Hills region. Helical pier and foundation repair is a major local industry.

Roof Condition: Wind & Hail Damagehigh

South Dakota experiences high wind events and regular large-hail storms, particularly in the spring and summer. Roof inspection for granule loss, bruising, and shingle lift is a primary concern on any property in the state.

Basement Moisture in Eastern SDmedium

Eastern South Dakota's glacial till clay soils retain water against foundation walls. Basement seepage and sump pump reliance are common in Sioux Falls and Aberdeen metro housing.
